Vulnerability from github – Published: 2022-04-21 01:57 – Updated: 2022-04-21 01:57

Details

The gtkui_conf_read function in src/interfaces/gtk/ec_gtk_conf.c in Ettercap 0.7.3, when the GTK interface is used, does not ensure that the contents of the .ettercap_gtk file are controlled by the root user, which allows local users to conduct stack-based buffer overflow attacks and possibly execute arbitrary code, cause a denial of service (memory consumption), or possibly have unspecified other impact via crafted lines in this file.

CVE-2010-3843 (GCVE-0-2010-3843)

Vulnerability from cvelistv5 – Published: 2021-05-28 12:14 – Updated: 2024-08-07 03:26

Summary

The GTK version of ettercap uses a global settings file at /tmp/.ettercap_gtk and does not verify ownership of this file. When parsing this file for settings in gtkui_conf_read() (src/interfacesgtk/ec_gtk_conf.c), an unchecked sscanf() call allows a maliciously placed settings file to overflow a statically-sized buffer on the stack.

Severity

No CVSS data available.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
